Penthera(TM) Enhances Mobile TV Revenue Opportunities Through Digital Fountain's FEC Technology; Provides Mobile Broadcast's First Implementation of Patented Algorithms to Ensure Fast, High Quality Filecasts.

PITTSBURGH -- Penthera Technologies, Inc., a software provider for mobile broadcast TV and multimedia, today announced it has implemented Digital Fountain's patented DF Raptor(TM) forward error correction (FEC) technology and incorporated it into Penthera's mobile broadcast software product line. Licensing the patented specifications of Digital Fountain's FEC technology, Penthera is the first commercial solution provider to bring to market their own "clean-room" implementation of Digital Fountain's Raptor algorithms. Through Penthera's implementation, mobile broadcasters and operators can now offer error free, mobile broadcast transmissions of revenue-generating media and data files. By utilizing Digital Fountain's DF Raptor FEC technology, which was made part of the global Digital Video Broadcast - Handheld (DVB-H) standard in 2005, such file broadcasts are sent faster, using less bandwidth and to a larger coverage area, when compared to other solutions.

"The integration of Digital Fountain's FEC technology with mobile broadcast has significant commercial implications for broadcasters and operators alike, enabling them to sell new services and applications to mobile device users," said Sam Leinhardt, CEO of Penthera. "Broadcasters and operators can now efficiently use a mobile broadcast network to offer a wide range of downloadable, fee-based programs and applications that require perfect fidelity. In addition to real-time broadcast content, broadcast networks can now generate revenues from services such as pay-per-view media, news and stock tickers, ring tones, Java applications, and other executable files."

Technology Challenges

Transmitting files via a uni-directional broadcast network creates a technical challenge: There is no return path to acknowledge receipt or request retransmissions if errors occur in the files which, in turn, would prevent operation. For real time video or audio broadcasts, this is not an issue since the TV or radio program is still received if a few transmission errors occur. Without an error-correction and loss replacement technology, broadcasters and operators could not efficiently offer filecasting services over a bandwidth-limited, uni-directional, broadcast network. Filecasting fidelity is a top requirement for a high performance mobile broadcast service, especially considering the revenue potentials for downloaded pay-per-view media, ring tones, games and other applications.

Digital Fountain's DF Raptor FEC technology offers an advanced and highly flexible type of FEC that enables the efficient and error-free download of multimedia data files in the presence of a wide range of network impairments. In addition, by employing DF Raptor FEC technology, multimedia content will be delivered complete and error free in a minimum amount of time across a wide coverage area, providing the opportunity to deploy a more cost-effective, high performance network. In addition to the standard for DVB-H networks, Digital Fountain's DF Raptor FEC technology is also part of the 3rd Generation Partnership Project's (3GPP) Multimedia Broadcast/Multicast Service (MBMS) specification for GSM-based 3G cellular networks.

An Intelligent Solution for New Revenue Sources

Penthera provides an end-to-end software solution that is provided to broadcasters, manufacturers, and cellular network operators worldwide. Penthera is the only mobile broadcast software provider who is currently offering their own, integrated implementation of Digital Fountain's DF Raptor FEC technology - a unique feat that significantly separates Penthera from other software providers - giving customers an early-to-market competitive edge.

"Penthera is proud of its mobile broadcast technology leadership in areas such as interactivity, advertising, FEC technology - and in the creation and implementation of an open standard, CBMS-compliant specification," said Adam Berger, Chief Technology Officer at Penthera. "We know that the mobile broadcast business case requires multiple revenue streams and we are creating the applications to drive those revenues."

Broad Appeal

Penthera is licensed to use Digital Fountain's DF Raptor FEC technology in multiple mobile broadcast methods, including DVB-H and Digital Mobile Broadcast (DMB), amongst others.

"Penthera realizes that Digital Fountain's DF Raptor FEC technology provides a key to creating innovative revenue opportunities for mobile broadcast deployments, much less key benefits such as increased bandwidth efficiency, faster download times and increased coverage area," said Charlie Oppenheimer, President and CEO of Digital Fountain. "Penthera has a fantastic team and is a wonderful company to work with. They really 'get it'. This is a significant milestone for Penthera and also a significant milestone for Digital Fountain."

Recently, Penthera announced that Modeo(TM) LLC, a subsidiary of Crown Castle International, Inc., has purchased Penthera Broadcast Center for use in Modeo's national DVB-H network operations center. Further, Digital Fountain recently announced that Modeo will also employ DF Raptor FEC technology as part of its overall DVB-H service, which is planned for the top 30 U.S. markets.
